Title:
  please upgrade 14.04 with the 8.1.2c+dfsg-5 version

Status in “tango” package in Ubuntu:
  Fix Released
Status in “tango” source package in Trusty:
  Fix Released

Bug description:
  [Impact]

   * It is not possible to use the event part of pytango. Only the
  polling part was working correctly.

   * all the depending packages (python-taurus and python-sardana) are
  unusable without this fix (they rely on the event part)

  [Test Case]

  This is took from the zeromq3 initial bug report
  (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=743508)

  this bug can be seens using the python-binding.
  But for htis you need a working tango database. So you need to install tango-db.

  apt-get install mysql-server
  apt-get install tango-db

  ~$ python
  import PyTango
  dev_name = 'sys/database/2'
  dev = PyTango.DeviceProxy(dev_name)
  cb = PyTango.utils.EventCallBack()
  id = dev.subscribe_event("state", PyTango.EventType.CHANGE_EVENT, cb, [], True)

  (waits forever... till  I press CTRL+C)

  the expected result is that the last line does not hang


  [Regression Potential]

   * no known regression.

   * in case of a regression only two packages can be affected (python-
  taurus and python-sardana)
